“This extension directly addresses a known attack on the BitTorrent protocol performed by some deployed network hardware. By obscuring the ip-port pairs network hardware can no longer easily identify ip-port pairs that are running BitTorrent by observing peer-to-tracker communications. This deployed hardware under some conditions disrupts BitTorrent connections by injecting forged TCP reset packets. Once a BitTorrent connection has been identified, other attacks could be performed such as severely rate limiting or blocking these connections.”
So, the new tracker peer obfuscation technique is especially designed to be a workaround for throttling devices, such as the Sandvine application that Comcast uses. More details on the proposal can be found at BitTorrent.org (http://bittorrent.org/), which aims to become a coordination platform for BitTorrent developers.
hats off to the devs for stepping up on this one. looking forward to see this feature implemented in transmission / azureus.
